Digital water flow thermometer.
These LCD digital thermometers have a metal temperature probe on the end of a 1metre long wire.
A small hole can be made in one of your pipes and the probe glued into place.

The thermometers can then be used to show the flow and return temperatures from your heat pump.
By viewing the flow and return temperatures, you can see that your heat pump is heating the pool water and by what amount.
The flow temperature also shows the water temperature in your pool which is a convenient way to see your pool temperature.
Units can be mounted in a wooden panel as per the example below (panel not supplied)
